double hot bar is a mod that allows us to use twice the space in the quick access bar, that is, where we place any object that we want to use with our character. Without this mod, Minecraft offers us a 9-slot hotbar. With this mod installed we will have double the space, that is 18 boxes.
By default, the new access bar will be placed just below the predefined bar, but we can also modify its position, placing one bar next to the other, creating a horizontal bar of 18 boxes. The way to navigate in these bars is always the same, using the mouse wheel.
This mod is in beta update phase, so it may still contain errors or bugs. We will publish their respective updates in this same article.
